Safe turbine operation

For safe turbine operation how many governors are generally required and Why?

Verified

Two independent governors are required for the safe turbine operation. One refers to an over speed or emergency trip that shuts off the steam at 10 percent above the running speed. The second, or main governor, generally controls the speed at the constant rate; though, several applications have variable speed control.
